What is the time period of a simple harmonic oscillator with a mass of 0.3kg and a force constant of 5N/m?

How are different types of energy used?

Inertia is hard to witness on Earth because: A. Magnetism is much stronger B. Gravity and friction are always acting on objects. C. Our mass is too small

Two loops of wire are arranged so that a changing current in one, the primary, will induce a current in the other, the secondary. The secondary loop has twice as many turns as the primary loop. As long as the current in the primary is steady at 3.

Using the first definition of coefficient of elasticity given in the lab (based on velocity), if a ball strikes a surface with a speed of 10 m/s and rebounds just after the collsion with a speed of 3 m/s, what is the coefficient of elasticity

The ultraviolet catastrophe is most closely associated with which phenomenon? A. Photoelectric effect B. Blackbody radiation C. Emission spectra D. Quantum mechanics

What is impossible for a machine to do? A) do a greater amount of work than the amount of work done on the machine B) apply a force in a direction that is different than the direction of the force applied to the machine C) move an object a greater

The phosphorus cycle keeps phosphorus availability naturally low. True or false?

Which best describes nuclear fission? A. A nucleus spontaneously splits and absorbs energy. B. Two nuclei spontaneously combine and absorb energy. C. A nucleus collides with a neutron and splits, releasing energy. D.

Which of the following is an example of conduction? A. A metal spoon becomes warm when placed in a cup of hot tea. B. Campers warm up while sitting by a campfire. C. A dog's bowl of water warms up out in the Sun. D.

Hink about the friction activity. Return to this activity to see it again if you need to. Explain what happened in each of the two demonstrations, and then compare them. Use the terms resistance, vacuum, gravity, velocity, and friction.
